Each chart shows one value per year; the dot marks the record year. TXx is the hottest daily maximum, TNn the coldest daily minimum, Rx1day and Rx5day the largest one-day and five-day rain totals, and CDD the longest run of days with less than 1 mm of rain. A year with missing days can understate an extreme.

Frost Dates and Growing Season

41 years with a frost

Across 41 years with a frost, the median last spring frost at Nacogdoches falls on 13 March and the median first autumn frost on 15 November, which leaves a median of 246 days between them.

Fitted over all years, the growing season changes by +3.2 days per decade at this station.

Frost dates and growing season at Nacogdoches
Measure	Median, all years	Earliest period	Recent period (1987 to 2023)	Recent against earliest	Fitted trend
Last spring frost	13 March	n/a	13 March	n/a	-2.0 days per decade
First autumn frost	15 November	n/a	15 November	n/a	+1.2 days per decade
Growing days	246 days	n/a	246 days	n/a	+3.2 days per decade

A frost day is a day with a daily minimum at or below 0 C (32 F). The last spring frost and the first autumn frost are the last and first such days of the cold season, and growing days are the days between them. A negative trend for the last spring frost means it comes earlier.

Rainfall Return Levels

49 years, 1974 to 2023

A day with at least 94.0 mm (3.7 in) of rain is expected about once in 2 years. A day with at least 215.5 mm (8.5 in) of rain is expected about once in 100 years.

Rainfall return levels at Nacogdoches: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	94.0 mm (3.7 in)
5 years	127.6 mm (5.0 in)
10 years	149.5 mm (5.9 in)
25 years	176.5 mm (6.9 in)
50 years	196.3 mm (7.7 in)	Longer than the 49 years of record
100 years	215.5 mm (8.5 in)	Longer than the 49 years of record

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 49 years of values from 1974 to 2023.

A return level is an estimate. It is least reliable for the long periods, 50 and 100 years, and for any period longer than the record behind the fit, where the fit has to reach past the largest day actually observed. It is not a forecast.

The largest wettest-day totals in the fit: 224.0 mm (8.8 in) in 2012; 193.8 mm (7.6 in) in 1975; 182.9 mm (7.2 in) in 1994.

No change in the annual mean temperature of this station was found against its neighbours.

Climate Twins

2009 to 2023 against 1961 to 1990

Over 2009 to 2023, Nacogdoches had a mean temperature of 19.0 C (66.2 F) and 1,140.9 mm (44.9 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Daingerfield 9 S (United States, 145 km away), Fairfield 3W (United States, 149 km away) and Livingston 2 NNE (United States, 101 km away).

Climate twins of Nacogdoches: stations whose 1961 to 1990 climate is closest to its 2009 to 2023 climate
Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Daingerfield 9 S	United States	145 km (90 mi)	19.2 C (66.6 F)	1,141.4 mm (44.9 in)	0.58
Fairfield 3W	United States	149 km (93 mi)	19.2 C (66.5 F)	1,027.8 mm (40.5 in)	0.71
Livingston 2 NNE	United States	101 km (63 mi)	18.8 C (65.8 F)	1,231.9 mm (48.5 in)	0.71

Twins are stations, not cities. A twin is one of the three stations at least 100 km away whose earlier climate is closest to this station's recent one, so a close match does not mean the two places look alike in other ways. A station move or a gap in a record can change that station's averages. The list describes past climate; it is not a forecast and does not say what caused any change. How twins are found, and a search for any station.
